It varies in different countries round the world but most use 240 volt mains.
It depends what country you're in. Here in the UK, the mains voltage is 230 volts.
The four main concepts of electricity are voltage (V), current (I), resistance (R), and power (P). Voltage is the electrical potential difference between two points, current is the flow of electric charge, resistance is the opposition to the flow of current, and power is the rate at which electrical energy is transferred.
live current may contain high voltage
A transformer for a doorbell works by converting high voltage electricity from the main power supply into lower voltage electricity that is safe for the doorbell to use. This lower voltage electricity is then sent to the doorbell to power it and make it ring when the button is pressed.
step up transformer output gives the high voltage which is useful for transmiission of electricity
step up transformer output gives the high voltage which is useful for transmiission of electricity
The standard electricity voltage in Brazil is 127 volts.
The standard voltage for electricity in Brazil is 127 volts.

Here are several. We don't know which one would be the 'main' one. Power = (voltage) x (current) (voltage)2 / (resistance) (current)2 x (resistance) (energy) / (time) (voltage) x (current) x (power factor)
no...current is a flow of electricity
There are three main properties that make electricity work: voltage. amps and resistiance. These properties work together inside a circus to allow electricity to move from place to place.
